Hi,

i would like to use AD8221 in one of my application, where idea is to amplify the differential potential recieved from 2 electrodes. To remove high frequency noise i use an RC filter just before the instrumentation amplifier input. do you think it is better to use a voltage buffer in between filter and amplifier input. In that case which analog device ic you suggest to use as a voltage buffer.

 

Waiting for the reply.....

 

Thank You
